This product is equipped with an AC
power inlet and must be connected to a
three-wire grounded plug.
The AC power cable must be plugged into an
appropriate outlet that is correctly installed
and grounded in accordance with all local
electrical safety codes and ordinances.
If hum or ground-buzz is induced into the
system, remove the rear-mounted GROUND
LINK. This ground-link isolates the AC
chassis ground from the audio ground. When
the LINK is removed, the AC ground remains
connected to the chassis via the AC inlet
connector and provides a direct path for any
electrical fault or dangerous condition.
Warning! No ground adapter should ever
be used with this unit.
3.3 AC Voltage Selection
Before connecting the Vt-747sp to the AC
supply, check the OPERATING VOLTAGE
located on the rear of the chassis in the
AC inlet connector.
Voltages available are 100-120-220-240VAC
+/-5%, 50-60Hz at 60 watts. (USA uses 120V)
To change the AC voltage for your location:
1. Make sure there is no AC power cable
connected to the AC inlet.
2. Insert a small flat-head screwdriver tip into
the voltage selector cavity. Carefully lift-open
the hinged cover from left to right.
3. Rotate the selector wheel to show the
correct voltage for your location, then push
the wheel firmly into the mounting tabs.
4. Press the voltage selector cover snap-shut,
check correct AC voltage in window.
5. Connect grounded AC power cable.
